Abstract

The cover consists of frame (10) and lid (20) connected by a sliding bolt (30). The bolt longitudinal axis slopes downwards to the circumferential edge of the lid at an angle, so that in an open position, the bolt occupies a higher position relative to the ground than in its locking position. The bolt and bolt guide are formed so that in an open position, the operative end (32) of the bolt projects over a surface (26) of the lid.
